dos_moment
(m, half_bandwidth)[source]¶ Calculate the m th moment of the Lieb DOS.
The moments are defined as \(∫dϵ ϵ^m DOS(ϵ)\).
- Parameters
- mint
The order of the moment.
- half_bandwidthfloat
Half-bandwidth of the DOS of the 2D Lieb lattice.
- Returns
- dos_momentfloat
The m th moment of the 2D Lieb DOS.
- Raises
- NotImplementedError
Currently only implemented for a few specific moments m.
